Difference between PJC and PVC.

[Riot_Queen]

Well for about a year not around the time I got pregnant with my last baby, I've been noticing weird feelings in my chest and infrequent, but very random times.
I've been looking into PVC and the symptoms are very similar to what I'm experiencing.
But my mother has PJC and I'm wondering if that's hereditary or not cuz we dunna her side of the family cuz she was adopted.
I've tried looking everywhere on the internet for symptoms of PCJ and all I'm getting is stupid stuff like "Premature Ejactulation." Ugh. Stupid internet.
I know PVC is lower ventricles an d PJC is the upper. But can anyone tell me the symptoms of PJC.
I can't go to the doc right now for insurance reasons and amd trying my best not to be stuck with yet another unpaid medical bill. Hopefully soon tho I'll be able to see a specialist.

The best invention in this century is the internet. It is good to research medical topics prior to visiting your Doctors. There are too many bad docs out there! We are always getting some knowledge about our medical condition ahead of seeing the our Doc.

Okay well this is what's been happening. The very last time it happened it felt like my heart blew up like a balloon, and then started this really weird like kind of a flopping around feeling side to side like a fish. And they were REALLY hard hard hard beats. Once it was over I was left breathless and dizzy.
Very scary.

Good news is is that I should be getting insurance within the next month or so, so I'll deff be bringing it up to my doc's attention.

Hello,

PJCs (premature junctional contractions) are what differs what you name PACs from what we (in Europe) call SVES (supraventricular extrasystoles). A PJC is a supraventricular extrasystole that origin in the AV node. It's correct what Itdood writes, a PJC is conducted through the His bundle and activates both ventricles at the same time. For all practical purposes, a PJC is similar to a PAC. It's completely benign, actually more benign than a PAC, because it doesn't have the similar abilities a PAC has; activating AV nodal reentry tachycardia (in those disposed to it).

Anyway, a PJC can be percieved quite dramatic, because it activate atrias simultanously (or sligthly after) ventricles, thus causing atrias to fire against closed triscupid- and mitral valves, making atrial blood backfire (a PVC can, too). This is not dangerous, but can create a "fullness sensation" in your throat.

PJCs are the most uncommon premature beats. PACs are more common by number of patients, but PVCs are more common by number (more people have large amounts of PVCs).

PJCs can be recognized on ECG by a narrow QRS complex similar to a PAC or sinus beat, without preceding P wave. (P waves can sometimes be seen after the QRS). In some cases, PJCs can create a wide QRS complex similar to a PVC (if one ventricle is still refractory) and can in those cases be hard to differ from PVCs.

I hope this cleared up some things. You have to stop reading cardiology topics on the internet, it's really not good for you.

did you try searching on "premature junctional contractions"?  I found info that way.

I may be wrong but I believe that PJCs and PVCs are both premature contractions of the lower part of the heart, the ventricles.

PVCs result from overactive ventricular pacer cells.  PJCs result from from within the AV node which normally fires the ventricles.  I gather that  PJCs will fire both ventricles at the same time, which is closer to a normal rhtyhm than a PVC is.  PVCs fire one ventricle at a time (though in qucik succession).
